- UNITED STATES PATENT OFFICEQ GINNING ANDDELINTING MACHINE.

Be it known that I, WVILLIAM D MoCor, a citizen of the United States of America, and residin at Brooklyn, in thecounty of Kings and btate of New York, have invented new and useful Improvements in Ginning and Delinting Machines, of which the followin is. a s ecification. a g a I My inventionrelates particularly to the treatment of seed cotton.

One object is to provide simple and compact mechanism for rapidly and completely separating long and short fiber fromthe seed. Another object is to provide in a single machine means for performing what are commonly termed the ginning and the y delinting operations which. are usually performed in separate machines.

In the form shown the invention contemplates a casing with a cylindrical member dividin it into an inner and an outer chamber. T is cylindrical member is made up of a plurality of suction creating plates and allow the seed to pass.

openings p blades with spaces between them permitting 25 the passage of the fiber buttoo small to A plurality of stripping members are arrangedadj acent the inner wall of this cylindrical member and the seed fiber is drawn into the inside of the cylinder suction or pressure. The fiber is "thus forced or drawn out through the The cylindrical member is rotated relative tothe stri pers and at high s eed so as to separate t e seed from the fi or which is beingsucked through the wall.

Preferably the upper part of the cylinder has it's blades vertical and the strippers adjacent thereto are constructed and arranged to knock off the seed from the longer fiber. The lower part of the cylinder has its plates horizontal and the strippers adjacent thereto are provided with an abrasive surface of emery or like a file so as to remove what are commonly; termed the linters.

The outer chamber is preferably divided into two arts so as to keep the longer fiber and-t e linters separate. a

The strippers are preferably arranged inclined and the cylinder is rotated so as to bring the seed against the under side of the 1 Specification of 1mm Patent.

I This frame iscarried strippers and thus allow the seed to move downward-as. soon asreleased. a y a The angular position of the stripping 55 members relative y to the cylinder, forces the seed downward and diagonally across. the faces of the blades and plates which cilitates the ginning action on the seed, 0 turning the seed so that the entire area of w the'seed is acted onby the ginning and dc linting members. i v v Ials prefer to employ a fan in the cylinder for assisting in opening the seed fiber 5g against the inner wall of thecylinderand strippers and augmenting the outward "cur-, rent of air between the horizontal plates in the lower partof the cylinder. 1 By rotating the cylinder with respect to" the stripper, the rotation of the; cylinder draws the air outward throughits wall as to suck the fibers from theinner to thej onterchamber. s a y Figure 1, is a side view and partial vertical section on the plane X--X of Fig.2.ofa machine embodyingtheimprovements'of, any invention'showing the ginning and delinting mechanism. i i T 1 0 i Fig. 2, is a fragmentary plan and partial ing parts of the ginning mechanism; a w I a yy 1g; 3, is a fragmentary verticalsectional View ofrpart of the delinting mechanism; 8

The casing has a standard 10, an outer shell 11 and a top piece 12. The seedfiber comes in through t e top opening 13 either a a by air pressureor suction. The ginned fiber passes out through the side flues14 and 15, the long fiber homing from the upper flue 14 and the short fiber or linters? from the, 1 lower flue 15. The seed passes outthe exit-g 16 at the bottom; i i a a The ginning cylinder has a bottom frame consisting of a ring '20 carried "byarms 21 in j by the shaft2'2 and supported by the jour-} nal 23 and the ste bearing 23'; The lower half of the cylin er-consists of a, plurality; so

of thin annular horizontal plates 24 with thin spaces 25 between adjacent plates for the fiber. The plates 24 may have their inner edges 24 finely serrated or toothed to increase the adhesive force on the fiber at the instant of ginning. The upper half consists of a plurality of spaced vertical blades 26 with the inner edge 27 of each forwardly proected and so close to the back of the next l-a e that seeds cannot pass through. The ring 28 forms the upper rim of the cylinder and the rin 29 forms the middle of the cylinder. T e three rings 20, 28 and 29 are tied together by rods such as 30. Washers such as 31 may be used to space the adjacent plates 21- apart. The shaft 22 and the ginning cylinder are rotated in the direction of the arrow at high speed, by any suitable means, as a belt 32. This rapid rotation draws the air and fiber outward between the plates and blades with great force. The shape of the blades 26 is such as to create a particularly powerful outward suction when the cylinder and bladesare rotated in the direction of the arrow shown in Fig. 2.

The strippers 35 are carried by the top plate 12 and are arranged at helical inclines just inside of the cylinder. The lower faces of'the upper portion of these strippers may be smooth, serrated or provided with steps adjacent the blades 26 to remove the seed from the long fiber which is held between the blades 26. If the under faces of the strippers are smooth as at 36' an effective shearing action is obtained. By making the edge scalloped as at 36' there is less shearing effect. By having the edge stepped as at 36 there is even less effective shearing and a more abrupt engagement with the seed and danger of breaking the seed by impact. An irregular edge however has the advantage of turningthe seed over and thus facilitating the removal of the fiber. To get the combined advantage some strippers may be smooth, some serrated and some stepped so that the seed fiber is subjected successively to the influence of all three varieties of actions. The lower faces of the lower portions of thesestrippersare provided with emery or small teeth like file teeth at 37 for removingthe lint. The lower ends of the strippers are connected by a ring 38.

A fan 40 may be provided on the shaft 22 for augmenting the circulatioi'i of air partlcularly between the plates 24 and serves to keep the seed fiber in motion. It also throws theseed fiber. out against the strippers and against the inner wall of the ginningcylinder. A partition 41 divides. the casing and fine into two parts on a'level with the center ring 29 so that the longer fiber may pass out the flue 14 and the linters through the flue 15. The bottom of the cylinder is formed by the inclined Hour 4 The rotary movement of this floor keeps the ginned seed in motion. The seed fall from the floor 42 onto the inclined floor 43 of the casing and thence out the exit 16. opening 16 draws back any unginned or only partially ginned seed fiber up into the cylinder where it has another chance to be gin'ned. The passage 16 may be controlled by a valve or door 44 for regulating the air outlet.

The operation is substantially as follows: The seed fiber is sucked through the opening 13 into the machine. The revolving cylinder generates an outward air current and the longer and lighter fibers are drawn out into the openings between the blades 26 and the seeds are knocked off from the fiber by the action of the strippers 35. The fiber then passes into the outer chamber and flue 14. The seeds having short fiber or linters fall or are forced down by the inclined strippers and are held against the plates 24 by the suction through passages 25 the action of the fan 40 and centrifugal force. The abrasive surfaces 37 and 24 on the strippers 35 and plates 24 take on the lint which is then drawn out through the openings 25 into the outer chamber and flue 15. The ginned seed fall or are gradually forced onto the bottom 42 of the cylinder and thence into the hop per-like construction below and thence down the incline 43 and out to the bins or suitable conveyer (not shown). The air drawn into the bottom lifts up any unginned seed or partially ginned seed back into the cylinder for further treatment. This insures the complete ginning and delinting of the entire mass of seed fiber in the single machine. The parts are so constructed that there is little to get out of order and but little wear.

The term cylinder as employed in the claims is intended to be construed broadly as a member rotatable about an axis even though the elements of its surface are not exactly parallel, as long as they extend generally in a longitudinal direction as for 1nstance, in a cone or frustum of a cone. The term vanes may be applied to the verticallycurved blades and also to the horizontal annular plates since both serve to force or draw the air outwardly from the inner chamber to the outer chamber.

It should be understood that I contemplate that many changes may be made in this construction without departing from the spirit or sco e of my invention.
